What I love about the city, is that as you wonder round it and explore it, you never know what you will come across. London in particular is a very fertile city that way. Central London is in a way considered the "front window" or "display" of the UK, and a lot of care has been put into its public space and buildings.
This photo was taken while walking along the river in Southwark near the Design Museum. Not only have the old buildings and warehouses been renovated and transformed into good looking and expensive apartments, but the public space and particularly the pedestrian route along the river has been beautifully done in a modern and understated way.
But you also have to have both your eyes and imagination open. This is just a simple little forgettable sculpture, yet it caught my eye immediately because it looked like a prehistoric fossil that has been uncovered and left in public for our perusal. As a sort of game or in joke of who will notice it.
